PAPER-ROLL-RELOADING DEVICE.

Application filed February 12, 1921.

To allwhomz'tmay concern:

Be it known that I, ()T'ro L. RAABE, a citizen of the United States, residing at Jersey City, county of Hudson, and State of New Jersey, have invented certain new and useful Improvements in Paper-Roll- Reloading Devices, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in paper roll supports for printing machines.

In multicouple machines where there are a number of decks of printing coupies the rolls for supplying the decks are usually arranged so that there is a running roll and a spare roll for each deck, so that the rolls may be changed or replenished while the machine is working, a spare roll being kept in readiness.

Where there are a large number of couples as in high speed machines, a large number of rolls are required. Where these rolls are superposed one above the other,

they rise to inconvenient heights for handling. When the rolls were superposed side by side so as to lessen the height difliculty has been experienced in changing the rolls of intermediate sets due to the fact that unless spaced very widely apart it was impossible to get a spare roll in under a roll which might be above it, and this particularly Where the roll nearest the machine was to be changed owing to interference of the web from a roll running on the outside.

It is the especial object of the present invention to produce a construction whereby a plurality of rolls may be supported in sets arranged side by side and superposed, a set being provided for each printing unit, such set including a spare and a running roll, the construction being such that any roll of any set may be easily and quickly changed while the machine is working with-' out increasing unduly the height at which the rolls are supported, so that a compact arrangement at the end of the press may be had and in which a web running from any of the rolls will not interfere with the changing or replenishing of the rolls,

With this and other objects not specifically referred to in view, the invention consists in certain novel parts and combinations, which will be described in connec-' Serial No. 444,513.

position occupied when a roll is being loaded thereon. I

Figure 3 is a plan view, partly broken away and partly in section of one of the sets of roll supports shown in Fig. 2.

Figure 4 is a side view of a construction shown in Fig. 3.

Referring now to these drawings, the invention has been illustrated in connection with a three roll machine, that is, a machine using three, rolls of paper at the same time. It will be understood, however, that the invention may be used with any arrangement emlploying superposed rolls.

eferring to these drawings, two printing units are illustrated which are supported in side frames 1 of any suitable construction. Each of. these units includesa pair of printing and perfectin couples 2, 3, 4, 5,

with the usual inking mec ianisms 6 therefor.

The printing mechanisms 2, are supplied, as shown, from a running roll. 7 and a spare roll 8 and the mechanisms 4, 5 are supplied from a running roll 9 and spare 10; a running roll 11 and spare 12 supply a third printing mechanism, not illustrated,

the webs being illustrated and marked- W, W W

In the construction embodying the invention the running rolls and spare rolls are arranged side by side in sets and superposed, and the rolls are supported so that any of the roll supports may be moved to clear a roll or roll support located above it'so that a roll of paper may bereadily loaded into the moved support without interference. The supports thus can be arranged superposed closely adjacent each other and a very compact and accessible arrangement provided for supporting a number of rolls.

Whilethe particular construction for supporting the rolls whereby this may be effectedmay be considerably varied, in the particular construction shown all the roll supports are shown as movable, though it will be understood that in machines where it is not desired to add any further sets of rolls the upper roll supports need not be made movable unless desired as the rolls can be loaded thereon, but this construction is preferred as it permits the inner roll of'any set to be loaded without interference from a web which may be running from an outer roll, as for instance, if it was desired to reload a roll in the supporting roll 7 when roll 8 was being used. As shown, therefore, all the roll supports are the same and the description of one will sufiice for all, the description of the supports for rolls 9 and 10 being given.

Each of the rolls 9, 10 is carried in a carriage 13, 14 which is movable in a main frame 15'. These carriages are movable sideways in the particular construction illustrated so that when the carriage 13, for instance, is moved it will clear a roll above it, as roll 7 and also a web running from roll 10. The frames 15 are, therefore, extended sideways. as indicated at 16 in Fig'. 4 to permit the carriages to be moved therein when thus moved sideways. The carriages each include a back frame 17 and side frames 18. Extending from each back frame is a pair of overhanging arms 19 which are, as shown in Fig. 4, spaced apart to form a clearance for loading the roll therebetween. These arms contain the bearings 20 for supporting the spindle orshaft 21 of the upper roll on which the roll rotates. These carriages are arranged side by side so that the arms extend face to face and toward each other, and in the best constructions there is a space 22 left between the ends of the arms on the two carriages so as to permit the spindle ends of a roll to pass between them, this construction being adopted so that in case both carriages of a set were drawn out into loading position at the same time a roll could be loaded into either carriage.

The carriages are mounted to have a sidewise sliding movement in the frames 15, 16. To permit an easy movement of the carriage so that it can be readily withdrawn and moved back into position, each carriage is supported on and moved along tracks with antifriction devices between the carriage frame and the tracks, and in constructions where the carriages are provided with overhanging arms, means are provided for preventing the carriages from tipping off the tracks. and the antifriction devices may be conveniently employed for effecting this.

" As shown, the carriage is provided with three sets of antifriction devices in the form of rolls 23, 24 and 25. These rolls run on tracks or rails 26 suitably secured in the machine frames -15, 16, before referred to. These rails are formed with bearing surfaces 27, 28 and 29. The bearing surfaces 27 and 29 are formedon opposite sides of the rails and the rollers 23 and 24 run on these tracks and thus prevent tipping of the carriages on the tracks. The upper rolls take against the bearing surfaces 28. The thrust caused by the Weight of the carriage and the roll is thus taken up by this arrangement and disposition of the rolls and easy running of the carriages is effected.

After a roll has been loaded into position in the carriage the carriage is moved to the left in Fig. 2 into operative position, and when in operative position is held locked. While these locking means may be of any desired character, in the particular ,construction shown, there is provided (see Figs. 3 and 4) a latch 30 on an arm 31 pivoted on a stud 32 in the carriage frame. This arm has secured thereto, as indicated at 33, a spring rod 34 provided with an operating handle 35. The spring normally tends to force the latch to closed position from which it may be moved by operating the handle 35.

The latch co-operates with a latch pin 36 carried between the arms of a yoke 37 on a movable block 38 slidingly supported on guides 39 on a bracket 40 fast in the frame of the machine 15, before referred to. The latch is provided with a guiding surface 41 which as the latch moves into position hits the pin, rides over it, and permits the latch to drop on to the pin, the carriage being thus automatically locked into position as it is moved into place.

In the best construct-ions means will be provided for adjusting the carriage slightly sidewise after it has been moved into locked position to permit the web to be brought into side registry or alignment with the other rolls of paper that are being run into the press. This is conveniently effected in the construction illustrated by means of an adjusting screw-42 taking into the yoke block 38, before referred to, this adjusting screw being operated against a thrust collar 43 by a hand wheel 44.

The rolls-may be driven in any suitable manner. As illustrated the roll spindles have a squared end 45 which enters a squared recess 46 in the end of a short shaft 47 supported in the frame 15, before referred to, this shaft at its other end being supported in a bracket 48 and driven by a pulley 49 or in any other suitable manner. The recess 46 and shaft 47 may be of sufficient depth to permit the slight'sidewise adjustment of the roll before referred to.

Suitable guides 50, 51 are provided for guiding the webs to the printing mechanisms, these guides being supported in any suitable manner, as-from arms 52 on the tracks or rails 26, before referred to, or supported from a top frame54 of the press.

carriages of each set are loaded with rolls,

essor? ne in each carriage and one at a time and the carriages are then moved into operating position. The Web of one roll, as 9, is led into its printing unit of the machine,'the other roll, as 10, being held in reserve. When the web from roll 9 nears its end it is attached to the leading end of the reserve roll which then becomes the running roll. The carriage for the expired roll is then 1 drawn out sideways and the old web roll spindle removed and a new roll loaded on the carriage and then moved into operating position to be held in reserve until the runnirg roll, as roll 10, has expired.

ith the construction described, it will be seen that either of the rolls in any of the sets may be changed without interfering with a roll above it, or with a web run- I ning above it, and a number of rolls can be arrangedin a very compact space and easily and readily handled.

While the invention has been described in its preferred form, it will be understood that various changes may be made in the mounting or supporting of the roll and the means for moving the rolls so as to clear a roll or web above it, and the invention is not to be limited to the construction shown and described.

What I claim is: 1.
